Webmaster of the SANTO 2006 blog about a scientific expedition of the National Museum of Natural History, Paris, France, to document the fauna and the flora, both marine and non-marine, of a large, rugged island in the South Pacific: Espiritu Santo (or Santo), in Vanuatu.
PhD-project:
"A biogeographical study of parasitic gastropods and their coral hosts in the Indo-west Pacific"
Within this study I am always very interested in acquiring wentletraps (snails that live associated with corals and sea-anemones; >100 species worldwide) on 70-96% alcohol from anywhere in the world, for reconstructing "the wentletrap phylogeny" with the help of DNA-sequencing. Like most ascidians these wentletraps have wide-spread distributions. Therefore the most important research questions of this project are: (1) whether gene flow and integrity of widespread species are maintained across the Indo-Pacific. (2) to what degree the snails and their coral hosts are co-evolving, and (3) whether the historical biogeography and geological timing of reconstructed speciation events can shed light on the evolutionary mechanisms that have led to the present diversity.
